The first time the problem appeared, it wouldn’t allow listing the leases. So I went to check the logs and this log showed up. I restarted the service, and less than a week later the same thing happened again.Does anyone have any idea why this error keeps happening, and what the possible consequences would be of increasing the maximum number of connections?
